ipv6 route bfd
Enables or disables BFD on IPv6 static routes.
Syntax
ipv6 route bfd [vrf vrf-name] [interval millisec min_rx min_rx multiplier role
{active | passive}]
To disable BFD on a IPv6 static route, use the no ipv6 route bfd command.
Parameters
• vrf vrf-name — Enter the keyword VRF followed by the name of the VRF to congure static route in that
VRF.
• interval milliseconds — Enter the time interval for sending control packets to BFD peers, from 100 to
1000. You cannot congure a value that is less than 100 milliseconds.
•
min_rx milliseconds — Enter the maximum waiting time for receiving control packets from BFD peers,
from 100 to 1000. Dell EMC recommends using more than 100 milliseconds.
• multiplier number — Enter the maximum number of consecutive packets that must not be received
from a BFD peer before the session state changes to Down, from 3 to 50.
• role {active | passive} — Enter active if the router initiates BFD sessions. Both BFD peers can be
active at the same time. Enter passive if the router does not initiate BFD sessions, and only responds to a
request from an active BFD to initialize a session.
Default
The time interval for sending control packets to BFD peers is 200 milliseconds.
The maximum waiting time for receiving control packets from BFD peers is 200 milliseconds.
The number of consecutive packets that must be received from a BFD peer is 3.
The BFD role is active
Command Mode CONFIG
Usage Information
• This command can be used to enable or disable BFD for all the congured IPv6 static route for specied VRF. If
VRF name is not specied the command will be applicable for default VRF.
Example
OS10(config)# ipv6 route bfd interval 250 min_rx 250 multiplier 4 role active
Supported releases 10.4.2E or later
show bfd neighbors
Displays information about BFD neighbors from all interfaces using the default VRF.
Syntax
show bfd neighbors [detail]
Parameters detail — (Optional) View detailed information about BFD neighbors.
Default Not congured
Command Mode EXEC
Usage Information Use the show bfd neighbors command to verify that a BFD session between neighbors is up using the default VRF instance. Use the detail parameter to view the BFD session parameters.
